Sensors:
Quantity: 8 temperature sensors + 2 pressure transmitters;
Type: PT100 platinum resistance thermometer and 4~20mA pressure transmitter;
Installation Location:
T1 Sensor: Compressor discharge temperature, PT100 platinum resistance thermometer, installed at the compressor discharge pipe outlet, used for monitoring discharge temperature, compressor overheat protection training
T2 Sensor: Condenser refrigerant outlet temperature, PT100 platinum resistance thermometer, shell-and-tube condenser refrigerant outlet (subcooling measurement point), used for calculating condensation subcooling
T3 Sensor: Expansion valve inlet temperature, PT100 platinum resistance thermometer, front end of the throttle valve, used for determining liquid temperature range
T4 Sensor: Evaporator refrigerant outlet temperature, PT100 platinum resistance thermometer, evaporator refrigerant outlet (superheat measurement point), used for calculating evaporation superheat
T5 Sensor: Compressor suction temperature, PT100 platinum resistance thermometer, compressor suction pipe, used for monitoring return gas temperature, preventing liquid slugging
T6 Sensor: Chilled water inlet temperature, PT100 T7 Sensor: Chilled water inlet pipe of evaporator, used for calculating the temperature difference between chilled water inlet and chilled water supply/return.
T8 Sensor: Chilled water outlet temperature, PT100 platinum resistance thermometer, chilled water outlet pipe of evaporator, used for calculating chilled water outlet temperature and cooling capacity.
P1 Sensor: High-pressure transmitter, 4-20mA pressure transmitter, compressor discharge/condenser inlet (refrigerant high-pressure side), used for monitoring condensing high pressure and high-pressure protection training.
P2 Sensor: Low-pressure transmitter, 4-20mA pressure transmitter, evaporator outlet/compressor suction side (refrigerant low-pressure side), used for monitoring evaporating low pressure and calculating saturated evaporation temperature.
